CVE-2025-65013: LibreNMS vulnerable to Reflected Cross-Site Scripting (XSS) in endpoint `/maps/nodeimage` parameter `Image Name`

November 18, 2025 (updated November 19, 2025)

A Reflected Cross-Site Scripting (XSS) vulnerability was identified in the LibreNMS application at the /maps/nodeimage endpoint. The Image Name parameter is reflected in the HTTP response without proper output encoding or sanitization, allowing an attacker to craft a URL that, when visited by a victim, causes arbitrary JavaScript execution in the victim’s browser.
